Cerebral alveolar hydatidosis: case report.

A young male patient, who previously was presumed inoperable due to an existing hepatic mass with multiple cerebral metastases, was referred to us from an oncology clinic ith signs of transtentorial herniation. An operation was performed promptly; the right parietal mass, which was totally removed, proved to be an alveolar hydatid cyst. He refused the operation proposed for the hepatic lesion and was discharged.
